Thanks everyone for your help.
I actually figured it out myself -
spaces get sent as "+" in a CGI form
commas get sent in their hex equivalent in a CGI form
so... i needed to convert my commas from their hex to their ascii equiv
first, and then do a character replace on both the plus and comma symbols
using a simple tr///;
So... i do my hex to ascii translation first, and the character replace
second.
so simple.
AARRRGH! :)
